6.7 Broil Element

The 240V 3800W broil (upper) element is attached to a reflector,
which helps to direct the heat evenly toward the food.
Refer to the Element Strip Diagram section to test the broil element at
the control module. A Broil Element Relay Test is also available in
Service mode. See the Service Mode section for details.
If the wires are disconnected from the element terminals, an
ohmmeter can be used to check for resistance of ~15 ohms.
